Given numbers are 870,818,470,245,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 870,818,470,245,707 is 82767125490.
Find LCM of 870,818,470,245,707 with Prime Factorization
| 2 | 870, 818, 470, 245, 707 |
| 5 | 435, 409, 235, 245, 707 |
| 7 | 87, 409, 47, 49, 707 |
| 87, 409, 47, 7, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 87 x 409 x 47 x 7 x 101 = 82767125490
Therefore, the lowest common multiple of 870,818,470,245,707 is 82767125490.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
870 x 818 x 470 x 245 x 707 = 57936987843000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
818 : 1, 2, 409, 818
470 : 1, 2, 5, 10, 47, 94, 235, 470
245 : 1, 5, 7, 35, 49, 245
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,818,470,245,707, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
818:2x 409
470:2x 5x 47
245:5x 7x 7
707:7x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5x 7 = 700
Therefore, the value for common factors is 700.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 57936987843000/(1x700)
LCM = 57936987843000/700
LCM = 82767125490
Thus, we can understand that the LCM of 870,818,470,245,707 is 82767125490.
